Solution Consultant (Business Analysis & Solution Architecture)

About the role

The organisation is expanding its architecture and procurement team to support multiple digital transformation projects from government agencies. This position works as a business owner representative, not a vendor representative. The primary responsibility is to receive requirements from government agencies, translate them into scopes that service providers can price accurately, prepare technical specifications in TOR/RFP documents, and assess the reasonableness of received proposals. The role sits between Business Analyst and Solution Architect, requiring the ability to analyse work processes, design preliminary architecture, and establish budget frameworks immediately from meetings with agencies. Projects rotate according to organisational priorities, covering diverse work types such as audit systems, central data platforms, public service systems, and cloud infrastructure design. The position holder must be ready to learn new domains quickly and not be tied to any specific area of expertise.
